applications entitled lVringers, one of which was filed June 1, 1920, under Serial Number 385,658, and the other of which was filed February 7,1921, under Serial Number 443,181, and has for its object to improve the same in the several particulars hereinafter noted.

To the above end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: I

The wringer frame illustrated is of the type shown in my co-pendingapplication S. N. 385,658, heretofore identified, but may be of the type disclosed in my later application and includes a pair. of laterally spaced uprights 6 having bifurcated upper ends in which is secured a top tie-bar 7, the

ends of which project outward of said uprights. Co-operating upper and lowerpres- Serial No. 447,129.

sure rolls 8 and 9, respectively, are provided with shafts 10 and 11, respectively, the former of which shafts is journaled in floating bearings 12 mounted between the prongs of the uprights 6, and the latter of which is journaled in fixed bearings 13 removably mounted between said prongs.

Loosely journaled on the left-hand end of the shaft 11 is a bevel gear 14 having in its hub lugs 15 adapted to enter notches 16 in a sliding clutch 17 mounted on said shaft and held for rotation therewith by a pin and slot 18. Also loosely mounted on the shaft 11, inward of the clutch 17,

is a collar 19 having, on its outer end, an outstanding flange 20. The clutch 17 is also provided, at its inner end, with an out-standing flange 21 and a coiled spring 22, en-

circling the shaft 11, is compressed between the clutch 17 and collar 19 and is under strain to yieldingly hold the clutch 17 interlocked'with the gear 14 to connect the same to the shaft 11. The gear '14 may be driven by any suitable driving mechanism not shown. Shifting mechanism for the clutch 17 includes a vertically disposed lever 23 intermediately pivoted. to a bracket 24 secured to the adjacent frame upright 6 and has, at its lower end, a fork .25 to receive, between the prongs thereof,

the two outstandingfianges 20 and 21 and hold the collar 19 as a base of resistance for the spring 22 and move the clutch 17 against the tension of said springto release the same from the gear 14. The pressure roll 8 is driven from the pressure roll 9 by intermeshing gears 26.

Pressure devices for the upper roll- 8 include coiled springs 27 seated in spring pockets 28 carried by sliding blocks'29 cast integral therewith and supported on the floating bearings 12. Flanges 30, on the sliding bearings 29, engage opposite faces of the uprights 6 and. guide said bearings for floating movement with the bearings 12. The pressure devices also include plungers 31 having, on their lower ends, spring caps 32 which rest on the springs 27 and work Within the spring pockets-28. On the upper ends of the plungers 31 are cylindrical head 33, which are free to move endwise in cylindrical seats 34 formed in the projecting ends of the top tie-bar 7. .The

plungers 31 are held against rotation, but

with freedom for endwise sliding move.- ment in the seats 34 by forming on the 'ly elongat sides thereof diametrically opposite vertical- -lugs which work in slots 36 formed i thesides of said seats, as best shown in Fig. 3. The heads 3301 the plungers, seats 34 and slots 36 are covered by caps 37 secured to said heads by screws. ,To render the pressure devices operative or inoperative, I provide a combined locking and releasing bar 38 mounted on the under face of the top tie-bar 7 for endwise sliding movement andheldrin position by screws 39 which extend through slots 40 in said bar and have screw-threaded engagement with the top tie-bar 7 The ,bar 38 is provided with apertures 41, on the sides of which are pairs of depending and longitudinally extended. cams 42 arrangedto engage diametrically opposite lugs 43. formed with the plunger heads 33 "and aligned with the lugs 35. When the bar 38 is moved to its extreme right-hand position, the apertures 41 are of such size as to permit the plunger I heads 33 and the lugs 35 and '43 to move "freely therein. A. left-hand movement of the bar 38 will'carry the cams 42 onto the lugs 43, depress the plungers 31-, which compress the s'prings 27 and thereby apply pressure to the rolls. As shown, the cams. 42 are formed by pressing the same directly from'the bar 38, but, of course, may be "formed in any other suitable way. u I

Endwise movement is imparted to the bar 38 to place the pressure devices undertension and release the same by a lever 44 preferably intermediately pivoted, as shown, to abearlng 45 secured to the upper face of the 'top tie-bar 7 and having'a depending arm to.- The lever 44, asshown, is in the form- 'of a rocker and extends longitudinally \in 46 which works in a slot rmed in sa d tie- I f bar and extends through a seat 47 formed' in thebar 38 to connect the lever v44'thererespect'to the bar 7 and its two extreme movements are limited by engagement of its outer ends with theupper face of the tie,-

liar7. The clutch 17 is'simultaneously opegated during the movement of the bar 38 byex tendin'g the upper end thereof into a seat 48 formedin the overlying portion of 'theb'ar38. v a

Yoke-like guards 49 for the gears 26 and the ends of the rolls .8- and 9,- are suspended by studs 50 from the sliding blocks 29. A

drain board 51' ispivotedto the uprights 6 for movement from one side of the-frame to the other.

The operation of the improved wringer may, be briefly described as follows: I In the drawings, the wringer is shown adjusted for work and, in which adjustment,

the right-handend of the lever 44isdepressed, which holds the bar 38 in it sflexi treme left-hand position-with its cams engagement with the lugs 43 and thereby looks the pressure devicesunder tension with held by the spring 22 interlocked with the gear '14 to connect said gear to the shaft 11. to drive the same, and which shaft 11, in turn, drives the shaft-10 to the gears 26.

In case the operators hand is caught in .the clothes being fed to the wringer and'is being drawn thereby to the pressure rolls, or in case his hand is actually caught between the rolls, he may instantly release the pres-. sure on'the rolls andstop the driving power to the rolls byv striking the raised or lefthand end of the lever 44 to' depress the same. This rmovement of the lever 44 will move the bar 38 to the right and thereby withdraw the cams om the'lug43, which releases the p gers 31 ,and permits the same to move upward in their seats 36 and the ap'ertures41 in said barunder the action of the springs 27, which, in turn, releases thepressure on the upper roll 8. The

movement of the bar 38 to the right also' rocks the-lever 23, which, by its fork engage ment with the flanges 20-and 21, shifts the clutch 17 and collar 19 axially on the shaft 11 and withdraws said clutch from the gear 14 and thereby stops the driving power to Q.

said shaft.

To. again put the rolls under'pressure and 7 start the driving action to the shaft '11, the

operator, by striking the right-hand or raised end of the lever v44, moves the.bar\

38 to the left, which causes the cams 42 to engage the lugs 43 and thereby depresses the ,plungers31 and places the springs 27 under tension. This movement of the bar case the notches 16 on the 'clutch 17 do not instantly mesh with the lugs 15 on the hub 38 to the left also rocksthe lever .23 to reof the gear 14 at the time the pressure 'de-' vices are place d under tension, the movement of the le 25 with the flange 20, bodilyto clutch. The other prong of the fork 25 will move away-from the clutch flange 21 and,

notches 16, the compressed spring 22will slide the clutch 17 on the shaft 11 and thereby cause the same .to interlock with the "gear '14 and'connect the same to the shaft 11.

er 23 will slide the collar 19, by the engagement of one of the prongs of its for v ward he clutch 17 and; thereby compress the -sprin'g 22 between said collar and After the operator has finished his, work with the improved wringer, it is only necessary to depress the raised left-hand end of "the lever 44v by striking the sametd, release 1 the pressure on the rolls and thereby increase-' I' the life thereof. This same movement also'fl'fl) sure rolls, of means for driving one of the rolls including a yielding set clutch, pressure devices for the rolls, an endwise movable combined locking and releasing bar for the pressure .devices, and a clutch-releasing lever directly and loosely connected to said bar and arranged, when said bar is moved into one position, to release the clutch and, when moved into another position, to per mit independent setting of the clutch.
